I am selling off the dash panel I have that I used to add a gauge to my truck. The panel has a 2" hole cut for a gauge... I'm sure with a little sanding you could get it to 2 1/16 if needed. The panel only has 4 small holes near the bottom where I mounted my brake control. If you have a prodigy brake control, the holes are already drilled.
I am including the rocker switch that is installed in the one block-off plate.
